我正在从Pixmap实例化一个FileHandle，该StorageManager指向来自Google的APK扩展库的OBB文件中的png文件，该文件使用Pixmap挂载。 OBB文件已加密。
这在我测试的运行Android 5.1和4.3但没有物理SD卡的设备上运行良好，但无法在运行带有物理SD卡的Android 4.4.1的设备上运行。我得到了：
加载pixmap时出错：解码器初始化失败了
这是整个堆栈跟踪：

我在Pixmap之前从同一个地方加载其他资源，它们在所有设备上都能正常运行;只是这一个Pixmap。
此外，如果我使用Gdx.files.internal（文件位于Android项目的“assets”文件夹中）从内部存储加载，则所有设备上的package com.sprhib.init;
import javax.servlet.FilterRegistration;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration.Dynamic;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.DispatcherServlet;
public class Initializer implements WebApplicationInitializer {
public void onStartup(ServletContext servletContext)
throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebAppConfig.class);
servletContext.addListener(new ContextLoaderListener(ctx));
ctx.setServletContext(servletContext);
Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
servlet.addMapping("/");
servlet.setLoadOnStartup(1);
FilterRegistration.Dynamic filterRegistration = servletContext.addFilter("encodingFilter",
new CharacterEncodingFilter());
filterRegistration.setInitParameter("encoding", "UTF-8");
filterRegistration.setInitParameter("forceEncoding", "true");
filterRegistration.addMappingForUrlPatterns(null,true,"/*");
}
}
都可以正常工作。
发生了什么事？
